Diether derivatives of homo- or substituted piperidines as non-imidazole histamine H3 receptor ligands
摘要:
Synthesis and biological activities of a series of homo- or substituted piperidine unsymmetrical diethers are described. The novel compounds were evaluated for histamine H-3 receptor binding affinities at recombinant human H3 receptor stably expressed in HEK-293 cells. All diethers showed in vitro affinities in nanomolar concentration range. The most potent compounds are 1-[3-(3-(4-chlorophenoxy)propoxy) propyl]-3-methylpiperidine 11 (K-i = 3.2 nM) and 1-[3-(3-(4-chlorophenoxy)propoxy)propyl]azepane 13 (K-i = 3.5 nM).
